AI agents call entire_checkpoint_rewind_list to retrieve information from Entire without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns information about available checkpoint rewind points without modifying any state. This is a read-only operation that simply enumerates existing checkpoints for inspection purposes.
From the tool's definition Tool name contains 'list' and description states 'List all available checkpoint rewind points' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available checkpoint rewind points for the current branch. Uses \. It is categorised as a Read tool in the Entire MCP Server, which means it retrieves data without modifying state.
Register the Entire MCP server in PolicyLayer and add a rule for entire_checkpoint_rewind_list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Entire. Nothing to install.
entire_checkpoint_rewind_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the entire_checkpoint_rewind_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for entire_checkpoint_rewind_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
entire_checkpoint_rewind_list is provided by the Entire MCP server (jurislm/entire-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
